Answer:

-\frac{104}{41}

Step-by-step explanation:

\frac{f(x)}{g(x)}=\frac{3-2x}{\frac{1}{x} +5}

To make this easier to deal with, we can plug in 8 first:

  • \frac{f(8)}{g(8)}=\frac{3-2(8)}{\frac{1}{(8)}+5 }
  • Then we can simplify the terms to get \frac{3-16}{\frac{1}{8} +5}=\frac{-13}{\frac{1}{8} +5}
  • The denominator of this fraction needs to have its own common denominator. To do so, we can multiply the 5 by \frac{8}{8} to give us: \frac{1}{8}+\frac{40}{8}
  • We can then simplify this to \frac{41}{8}
  • Now putting this back into our original fraction we have: \frac{-13}{\frac{41}{8} }
  • This is also equivalent to \frac{(\frac{-13}{1} )}{(\frac{41}{8} )} which means we need to take the whole denominator of the fraction and flip it and multiply it by the numerator to get: \frac{-13}{1}*\frac{8}{41}
  • This then simplifies to \frac{-104}{41}

Identify the coordinates that result when the point (−4, 5), is translated 8 units right and 3 units down. HELP ASAP!
pochemuha

Answer:

The answer is (4,2)

Step-by-step explanation:

in the point (-4,5) X=-4 AND Y=5

so if you move 8 units right, the X increases by 8(because the  the x axis is left and right) so X transform into 4= -4+8=4

With Y(the y axis is up and down) whe u go 3 units down un decrease the number so Y transforms into 2== 5-3=2

The new coordiantes are(4,2)

A distribution has the five-number summary shown below. What is the range of this distribution? 24, 36, 42, 57, 65
inn [45]
Hello!

To find the range of the distribution, we must order the data from least to greatest (it has already been done) and then subtract the smallest value from the largest value in the set.

In this set, the smallest value is 24, and the largest value is 65. Subtract:

65 - 24 = 41

A N S W E R:

The range of the distribution below is A. 41.

Inga [223]

Answer:

90

Step-by-step explanation:

The sum of squares of the deviation from mean=sum(x-xbar)²=?

x

12

6

15

9

18

12

xbar=sumx/n

xbar=(12+6+15+9+18+12)/6=72/6=12

x      x-xbar       (x-xbar)²

12      12-12=0     0

6       6-12=-6     36

15      15-12=3      9

9       9-12=-3       9

18      18-12=6      36

12      12-12=0      0

sum(x-xbar)²=0+36+9+9+36+0=90

So, the sum of squares of the deviations from the mean is 90.
